Initial Engine Start

the transmission is in neutral and turn

computer diagnosing the system
to ensure everything is functional,
including the light bulbs for the
warning lights. If everything is
OK, both lights will go out in
approximately five seconds.
Start the engine
after
the lights go
out. If starting a vehicle, start the
engine with foot
off
the foot pedal.
